Early life undernutrition and adolescent pregnancy outcome in rural India

Maternal risk factors associated with term low birth weight in India: A review

Low birth weight is one of the leading factors for infant morbidity and mortality. To a large extent affect, various maternal risk factors are associated with pregnancy outcomes by increasing odds of delivering an infant with low birth weight. Despite this association, understanding the maternal risk factors affecting term low birth weight has been a challenging task. To date, limited studies have been conducted in India that exert independent magnitude of these effects on term low birth weight. The aim of this review is to examine the current knowledge of maternal risk factors that contribute to term low birth weight in the Indian population. In order to identify the potentially relevant articles, an extensive literature search was conducted using PubMed, Goggle Scholar and IndMed databases (1993 – Dec 2020). Our results indi­cate that maternal age, educational status, socio-economic status, ethnicity, parity, pre-pregnancy weight, maternal stature, maternal body mass index, obstetric history, maternal anaemia, gestational weight gain, short pregnancy outcome, hypertension during pregnancy, infection, antepartum haemorrhage, tobacco consumption, maternal occupation, maternal psychological stress, alcohol consumption, antenatal care and mid-upper arm circumference have all independent effects on term low birth weight in the Indian pop­ulation. Further, we argue that exploration for various other dimensions of maternal factors and underlying pathways can be useful for a better understanding of how it exerts independent association on term low birth weight in the Indian sub-continent.

Determinants of Stunting at 6 Weeks in the Northern Cape Province, South Africa

The first 1,000 days from conception to 24 months is a critical period for healthy growth and development. In South Africa, stunting (weight-for-length below −2SD from the WHO reference mean) is a major public health issue with significant health consequences. We determined associations between demographic, health, and anthropometric indicators of mothers and their infants. A cross-sectional study was conducted in the Northern Cape. All mothers with 5- to 7-week-old babies visiting PHC facilities were invited to participate. A questionnaire was completed in a structured interview with each mother. Age and length of the baby at 6 weeks were used to determine stunting, while the weight and height of the mother were measured for body mass index (BMI). Eight hundred questionnaires were completed in 92 facilities. The median age of mothers was 26 years (IQR 20–30 years) and 44.9% were married. Only 40.1% had completed school or tertiary education and almost 40% relied on a government grant as the main source of income. Two-thirds (64.9%) had not planned the pregnancy and 17% were on antiretroviral therapy (ART). More than a quarter (26.1%) smoked cigarettes or used snuff during pregnancy, while 9.4% drank alcohol. At 6 weeks, 31% of boys and 14% of girls had a length-for-age below the WHO reference values, while 25.4% of mothers were classified as obese and 24.6% as overweight. More than 70% had a waist circumference above 80 cm. Significantly more mothers with stunted babies weighed less [−6 kg; −1 kg] and were shorter [−4 cm; −1 cm] than mothers with babies who were not stunted. Compared to babies who were not stunted, significantly more babies of mothers who lived in informal housing [−19.7%; −3.2%], relied on a grant [−19.7%; −3.2%], smoked/ snuffed [7.6%; 23.5%], and used alcohol during pregnancy [0.3%; 11.5%] were stunted. The following factors significantly increased the risk of having a stunted baby at 6 weeks: living in informal housing vs. formal housing (RR: 0.68, 95% CI [0.5; 0.9]); smoking or using snuff during pregnancy (RR: 1.74, 95% CI [1.3; 2.3]); using alcohol during pregnancy (RR: 1.5, 95% CI [1.1; 2.2]); both smoking and using alcohol during pregnancy (RR: 1.97, 95% CI [1.4; 2.9]). We confirmed the coexistence of under- and over-nutrition among mothers and their babies, possibly indicating that stunting in childhood may predispose to overweight and obesity in adulthood in a vicious cycle that affects generation after generation. Interventions aimed at poverty alleviation and encouraging healthy lifestyles with an emphasis on healthy eating, smoking cessation and abstaining from alcohol before pregnancy are urgently required.

Global burden of maternal and child undernutrition and micronutrient deficiencies

Maternal and child undernutrition and micronutrient deficiencies affect approximately half of the world's population. These conditions include intrauterine growth restriction (IUGR), low birth weight, protein-energy malnutrition, chronic energy deficit of women, and micronutrient deficiencies. Although the rates of stunting or chronic protein-energy malnutrition are increasing in Africa, the absolute numbers of stunted children are much higher in Asia. The four common micronutrient deficiencies include those of iron, iodine, vitamin A, and zinc. All these conditions are responsible directly or indirectly for more than 50% of all under-5 deaths globally. According to more recent estimates, IUGR, stunting and severe wasting are responsible for one third of under-5 mortality. About 12% of deaths among under-5 children are attributed to the deficiency of the four common micronutrients. Despite tremendous progress in different disciplines and unprecedented improvement with many health indicators, persistently high undernutrition rates are a shame to the society. Human development is not possible without taking care to control undernutrition and micronutrient deficiencies. Poverty, food insecurity, ignorance, lack of appropriate infant and young child feeding practices, heavy burden of infectious illnesses, and poor hygiene and sanitation are factors responsible for the high levels of maternal and child undernutrition in developing countries. These factors can be controlled or removed by scaling up direct nutrition interventions and eliminating the root conditions including female illiteracy, lack of livelihoods, lack of women's empowerment, and poor hygiene and sanitation.

Social dimensions related to anaemia among women of childbearing age from rural India

OBJECTIVE

To examine various sociodemographic aspects related to consumption of micronutrient-rich foods like green leafy vegetables (GLV), which will be helpful in modifying dietary habits, a strategy that merits consideration for prevention of anaemia.

DESIGN

Cross-sectional study for collecting data on socio-economic and anthropometric (weight, height) variables, Hb, dietary pattern (FFQ) and peripheral smear examination for classifying nutritional and iron-deficiency anaemia (IDA).

SETTING

Three villages near Pune city, Maharashtra, India.

SUBJECTS

Rural women (n 418) of childbearing age (15-35 years).

RESULTS

Mean Hb was 11·07 g/dl. Seventy-seven per cent of the women were anaemic (Hb < 12 g/dl) and 28 % had IDA, indicating that a large proportion of the women had nutritional anaemia. Higher prevalence of IDA was associated with several sociodemographic and maternal parameters, but multiple logistic regression analysis showed significant (P < 0·05) risk of IDA with lower body weight (<40 kg), short maternal height (<145 cm), younger age at marriage (<19 years) and higher parity (≥ 2). Various socio-cultural reasons associated with low consumption of GLV included non-cultivation of GLV, priority for selling them rather than home consumption, dislike of GLV by husband and children, and lack of awareness about different recipes for GLV.

CONCLUSIONS

Our findings highlight that low consumption of GLV, which are treasures of micronutrients including Fe, is associated with genuine social reasons. This indicates a need for developing action programmes to improve nutritional knowledge and awareness leading to enhanced consumption of Fe-rich foods for preventing anaemia in rural India.
